Floating grid arrangement to support and position decorative elements

ABSTRACT

Plastic grid or framework arrangements are used to support and position of bowls that hold flower arrangements, candles, letters, and other decorative elements. These grids are deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. The grid themselves do not float, and are positioned below the surface of the water, and thus are not readily visible. Buoyancy is provided at the hubs that form nodes in the grids. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain.

DETAILED DESCRIPTION

During the course of this disclosure like numbers will be used toidentify like elements according the different views of the disclosedembodiments.

FIGS. 1A-1C show a triangular grid framework for supporting decorativeflower holder bowls 18 using hubs 12 that have six spoke engagingpockets 32 according to the embodiment 10. The bowls 18 support flowers16, or candles, or other decorative objects. Spokes 14 connect to thehubs 12 in a series of repeating patterns suggestive of triangles.

FIGS. 2A-2C show an alternative framework arranged in the form of a ring20.

FIGS. 3A-3E illustrate details of the six pocket hub 12 and furtherindicating how the spoke retention spring clips 34 are inserted into andpermanently attached in each of the hub pocket 44. Each hub 12 includesa top side 24, a base 26, a sidewall 28 and a hollow central aperture30. Six slots 32 are located evenly spaced around the sidewall 28. Sixspringy clips 34, described in detail in FIGS. 17A-17E, are insertablein the pockets 44 as seen in FIGS. 3E and 3D. The clips 34 include aflat first arm section 36, a flat bottom section 38 and a secondopposing arm section 40. Second arm section 40 includes a convex bump 42that selectively engages the detent 60 on the spoke end cap 22 shown infurther detail in FIGS. 7A-7F. Each of the pockets 44 includes anaperture 46 for framing the protruding bump 42 which in turn is engageswith the detent 60 on the end cap 22. The top 24 of the hub 12 includesa circumferential flat flange portion 48 and a downward side panel 50that depends therefrom. The six pockets 44 on the hub 12 are spaces 60degrees apart and, accordingly, can be used to form triangular gridframeworks as shown in FIGS. 1A-1C or the circular framework of FIGS.2A-2C.

FIGS. 4A-4C illustrate a square grid framework 52 which can be formedwith hubs 54 which only have four pockets or slots 54. Details of a fourpocket hub 54 are shown in FIGS. 5A-5F. It is similar in construction tothe six pocket hub 12 except that it has only four pockets 44 evenlyspaced 90 degrees apart.

FIGS. 6A and 6B illustrates the manner in which the spoke ends 22 slidesinto slots 32 then engage the retention spring 34 in the pockets 44 of afour pocket hub 52. As shown in FIGS. 7A-7F each spoke end cap 22includes a top, head section 56, a pin-like portion 58 and a concavedetent 60 for selectively engaging the bump 42 on the retention spring34. A spoke receiving pocket 62 is located in the head 56 of the spokeend cap 22. Downward pressure on the end cap head 56, as seen in FIG.6A, forces the pin section 58 into the pocket 32 until the pin 58 iscompletely inserted into the pocket 32 and is held in that position bythe engagement of convex bump 42 with concave detent 60. Disassembly isaccomplished by pulling up on the spoke cap head 56 until the force issufficient to case the bump 42 to disengage from the detent 60.

FIGS. 8A-8C illustrates how a decorative element support bowl isattached to a hub 54 and how the spokes 14 radiate from the hub 54. Alsoshown is a bowl 18 including a float chamber 64 located in the center ofthe bowl. The bowl 18 also locks the spoke ends 22 in position inpockets 32 of hubs 54. The basic frame including the hub 54 and spokes14 are intended to remain just below the waterline and are not readilyseen. The float chamber 64 located in the center of the bowl 18 and inconjunction with the buoyancy of the bowl 18 itself causes the apparatusto float in such a manner that only the bowl 18 is visible above thewaterline.

FIGS. 9A-9C illustrate the hub 54 and spoke frame arrangement of FIGS.8A-8C with the decorative bowl 18 replaced by a separate float element65 visible above the hub. There are circumstances where it may bedesirable not to have a decorative element support bowl 18 at a hub nodebut need to have the rest of the framework in place and in a balancedposition just below the waterline. In this embodiment the float 65 alonelocks the end caps 22 in position in pockets 32 of hub 54.

FIGS. 10A-10F illustrates details of a bowl subassembly 18 having achamber 64 located in the center thereof and also illustrates thelocation of four dogleg tabs 66 for engaging via rotating motion thecircumferential flat flange portions 48 of the four spoke hub 54.

FIGS. 11A-11E illustrates another embodiment of the decorative bowl 72in which the bottom of the float is formed by the bottom of the bowl 18.

FIGS. 12A-12F show different views of a float subassembly 65. Float 65includes dogleg tabs 66 for engaging that flange portions 48 of the fourspoke hub 54.

FIGS. 13A-13E illustrates the base 80 of a float and FIGS. 14A-14Eillustrate the top 82 which mates with base 80 to form float 65 shown inFIG. 12F. The top 82 of the independent, standalone float 65 is also thesame as the top 82 of the float chamber 64 in bowl 18 and can be weldedor bonded by conventional means to base 80 or the bottom of bowl 18. Theseal or bond is hermetic so the bowl 18 does sink or fill with waterfrom below.

It is clear from the above that the float can either be stand alone andseparate as in embodiment 65 or can be integrated into the structure ofthe bowl 18 itself where the bottom 64 of the bowl 72 forms the bottomof the integrated float as seen in FIGS. 11A-11E.

A typical straight spoke 14 is shown in FIGS. 15A-15C. Spoke 14 has anhour glass-like shape and includes a top rib 84, and intermediateconnecting section 86 and a bottom rib 88. The shape is the inverse ofthe shape of the opening 62 in the end cap 22 so that the two mate andstay mated due to the force of friction or by means of thermal oradhesive bonding.

FIGS. 16A-16E show a typical spoke 14 with a pair of end caps 22attached.

As previously described, FIGS. 17A-17E illustrate the U-shaped lockingleaf-type retention spring 34 including the convex bump 42 which isreceived in the hub pockets 44 and hold the end caps 22 of the spokes 14in properly assembled position.

FIGS. 18A-18C and 21A-21C illustrate a ring embodiment in which verticalextenders 94 can be used to raise the height of the decorative bowl 18substantially above the height of the water surface. Horizontalextenders 96 can also be used to extend the framework in a planehorizontal to the water surface and the plane of the rest of theframework. Curved spokes 92 are used to connect the hubs 54 together toform a relatively smooth ring-like structure. FIGS. 19A-19D illustratethe alternative embodiment in which the spokes 92 are curved and FIGS.20A-20D illustrate the manner in which the curved spoke 92 of FIGS.19A-19D engages a four pocket hub 54.

The embodiments typically can be used in the following manner. First,the user determines the size and shape of the framework array and thenumber and type of decorative items based on the size and shape of bodyof water and the specific objectives of the display. Second, using thekit of components, the grid is assembled next to the body of water bysnapping the spokes 14 into the hubs 12 or hubs 54. Third, the spokes 14are than locked into place using either a standalone float subassembly65 or a bowl 18. Fourth, the decorative elements 16 are attached to orcontained in the bowls 18. Additional bowls 18 can be attached to thespokes 14 in between hubs 12 if required. As the array is assembled, itcan be slid into the water. The array can also be assembled in thewater.

If required, additional spokes 14 can be added on the outside of thearray in order to locate the decorative elements 16 in bowls 18 awayfrom the edge of the pool or fountain. In an open body of water, anchorscan be attached to the array in order to keep it in place.

When no longer in use the decorative array 10, 20, 52, 90 and 98 caneasily be removed from the water and disassembled for storage and futureuse.

The floating grid arrangements disclosed herein have advantages over theprior art, such as but not limited to:

A. The grid is formed using plastic materials with a specific gravitygreater than 1.0. These materials can be transparent or colored to matchthe bottom of the pool.

B. The spokes 14 can be formed in various lengths in order to providemaximum flexibility in the configuration of the array. The spokes haveend fittings or caps 22 that are permanently attached. These caps 22enable quick attachment to the hubs 12, 54 in such a way as to stabilizethe grid framework during assembly.

C. The spokes 14 snap into the hubs 12, 54 from above and are retainedby spring clips 34 pre-assembled into the hubs 12, 54. The spokes 14 arefurther locked into position when the float subassembly 65 or a bowl 18is locked into place on the top of the hub 12. The bowls 18 will holdthe decorative elements 16 and the floats 65 can be locked into place ontop of the hubs 12, 54 where no bowls are required.

D. It is possible to attach bowls 18, with decorative items 16 in them,to the spokes 14 in between the connecting hubs 12.

E. The floats 65 and the bowls 18 provide the buoyancy to keep the gridfrom sinking too far below the surface of the water.

F. The size and configuration of the grid is quite variable according tothe number of hubs 12, 54 and lengths of spokes 14 and 92.

G. Hubs 12 with six (6) evenly spaced slots 32 will produce a hexagonalarray. Hubs 54 with four (4) evenly spaced slots 32 to hold spokes 12will produce a rectangular array.

H. Curved spokes 92 will produce a circular array. The radius ofcurvature will define the overall size of this array.

I. Vertical extension fittings 94 can be attached to bowls 18 to providea platform for decorative arrangements at various heights above thesurface of the water.

J. Once the array is constructed with the spokes 14, 92 locked intoplace in the hubs 12, 54 the whole grid can be maneuvered easily. Thisallows for construction of the grid on land and so it can to be easilyslid into the water for final positioning.

K. If required the grid can be easily modified once it has been deployedin the water.

L. The locking mechanism that keeps the elements of the array in placeis unique and easy to use. In the case of a bowl 18 and hub 54, thelower protruding portion 64 acts as a pilot to guide into the slottedcylindrical opening 30 after the spoke caps have been inserted intopockets 32 and held in place by springs 34. Once the base of float 64 ofbowl 18 is fully seated, the bowl is rotated about 60° so that the doglegged tabs 66 engage the underside of top flange 48 and are held inplace by friction and/or the natural springiness of the plasticcompartments. Additional security can be obtained by adding a small ribor bump (not shown) to the underside of flange 48 so the tabs 66 don'tback out. The locking with a standalone float 65 is accomplished inexactly the same way, namely, the base 80 is inserted in the slottedcylindrical opening 30 and then rotated until the dog legged tabs 66fully engage the underside of the top flange 48.

FIGS. 22-37 depict an alternative embodiment in the form of a floatingapparatus 98 for supporting decorative elements in water, with analternative arrangement for retaining the spokes and the bowl. Thefloating apparatus 98 includes a hub 100; a decorative element supportbowl 102; four spoke end fittings 104; a bowl adapter 106; and a float108. The floating apparatus 98 is configured to be connected to four ofthe spokes 14. Alternative embodiments of the floating apparatus can beconfigured for connection to more, or less than four spokes 14.

The floating apparatus 98 is configured so that each spoke 14 can beconnected to the hub 100 via a single spoke end fitting 104, without theneed for a separate, additional piece such as the above-described spokeretention spring clip 34.

The hub 100, bowl 102, spoke end fittings 104, bowl adapter 106, andfloat 108 can be formed from a thermoplastic or thermosetting material;other types of materials can be used in the alternative. The float 108can be a float chamber mounted in the center of the bowl 102, asdepicted in FIG. 23 (for clarity of illustration, the float 108 isdepicted in FIG. 23 only). Alternatively, the float 108 can be formed bythe bottom of the bowl 102.

References to directional terms such as “above,” “below,” “upper,”“lower,” etc. are made in reference to the component orientationsdepicted in FIG. 22 . These terms are used for illustrative purposesonly, and unless otherwise noted, are not intended to limit the scope ofthe appended claims.

As can be seen in FIGS. 26 and 27 , the hub 100 includes an outer wall110 having four rounded corner portions 112, and four planar portions114. Each planar portion 114 is disposed between, and adjoins anassociated two of the corner portions 112, so that each planar portion114 is oriented at an angle of about 90 degrees in relation to itsadjacent planar portions 114. The planar portions 114 each have a slot116 formed therein. The slot 116 extends downward, from an upper edge ofthe planar portion 114.

The hub 100 also has a plurality of interior walls 120, as shown inFIGS. 26, 27, and 29 . An end of each interior wall 120 adjoins anassociated planar portion 114 of the outer wall 110. The interior walls120 and the planar portions 114 define pockets 122. Each pocket 122receives an associated one of the spoke end fittings 104.

Referring to FIGS. 26 and 27 , the interior walls 120 and the planarportions 114 of the hub 100 define slots 123. Each slot 123 extendsdownward from the upper edge of its associated interior wall 120. Theslots 123 have a height, or vertical dimension, that is less than theoverall height of the interior walls 120. Two of the slots 123 areassociated with each pocket 122. The two slots 123 associated with eachpocket 122 adjoin, and are disposed on opposite sides of the pocket 122.

Each interior wall 120 includes a plurality of tabs 124 disposed alongthe bottom edge of interior wall 120, as can be seen in FIG. 29 . Thetabs 124 are configured so that two of the tabs 124 are associated with,and are located on opposite sides of each pocket 122.

Referring to FIGS. 30-32 , each spoke end fitting 104 includes an upperportion 130 and an adjoining lower portion 132. The upper portion 130has an opening 134 formed therein. The opening 134 is configured toreceive the spoke 14. The opening 134 has a shape that substantiallymatches the cross-sectional shape of the spoke 14; and the opening 134is sized so that the spoke 14, once inserted in the opening 134, isretained in the opening 134 by an interference fit between the spoke 14and the upper portion 130.

The lower portion 132 of the spoke end fitting 104 includes twosidewalls 136; two indented portions 138; and an end portion 140. Anupper end of each sidewall 136 adjoins the upper portion 130 of thespoke end fitting 104; and a lower end of each sidewall 136 adjoins arespective one of the indented portions 138. The end portion 140 iscurved. Each end of the end portion 140 adjoins a respective one of theindented portions 138. As can be seen in FIGS. 30 and 31 , each indentedportion 138 is curved inwardly, so that the indented portion forms adepression 139.

Each spoke end fitting 104 also includes two web portions 142, as can beseen in FIGS. 30-32 . The web portions 142 adjoin, and extend outwardlyfrom opposite sides of the upper and lower portions 130, 132 of thespoke end fitting 104. The web portions 142 are configured to bereceived by the slots 123 when the spoke end fitting 104 is insertedinto its associated pocket 122. The web portions 142 have a height, orvertical dimension, that is approximately equal to the height of theslots 123.

Each spoke 14 is connected to its associated hub 100 by a spoke endfitting 104. The spoke end fitting 104 is connected to the spoke 14 byinserting an end of the spoke 14 into the opening 134 in the upperportion 130 of the spoke end fitting 104, as can be seen in FIG. 33 .The spoke end fitting 104 and the spoke 14 then can be connected to thehub 100 by aligning the end portion 140 of the spoke end fitting 104with one of the pockets 122 in the hub 100, and moving spoke end fitting104 toward the pocket 122.

The movement of the spoke end fitting 104 toward the hub 100 initiallycauses the end portion 140 of the spoke end fitting 104 to becomedisposed in the pocket 122. Continued movement of the spoke end fitting104 causes the lower portion 132 of the spoke end fitting 104 to enterthe pocket 122, and the web portions 142 to enter their associated slots123 in the hub 100. Further movement of the spoke end fitting 104 towardthe hub 100 causes the upper portion 130 of the spoke end fitting 104 tobecome disposed in the pocket 122. As can be seen in FIG. 27, the slot116 formed in the adjacent planar portion 114 of the hub 100accommodates the spoke 14 as the upper portion 130 enters the pocket122.

The end portion 140 of the spoke end fitting 104 contacts the tabs 124on the hub 100 as the spoke end fitting 104 approaches itsfully-inserted position within the pocket 122. The curvilinear shape ofthe end portion 140, in conjunction with the resilience of end portion140 and the sidewalls 136, cause the end portion 140 and the sidewalls136 to flex inwardly as the end portion 140 passes over, and is urgedinwardly, by the tabs 124. Once the end portion 140 has passed the tabs124, the end portion 140 and the sidewalls 136 return, or spring back,to their un-deflected states. This movement causes the tabs 124 tobecome disposed within the depressions 139 defined by the adjacentindented portions 138 of the spoke end fitting 104.

At this point the web portions 142 have reached the extent of theirdownward travel in their respective slots 123; and interference betweenthe lower ends of the web portions 142 and the bottom surface of theassociated slots 123 prevents further downward movement of the spoke endfitting 104 and the attached spoke 14.

The spoke end fitting 104 is held in the pocket 122 by interferencebetween the tabs 124 and the adjacent surfaces of the indented portions138, which discourages upward movement of the spoke end fitting 104 inthe pocket 122.

The spoke end fitting 104 can be removed from the pocket 122 by pullingupwardly on the spoke 14, or by pushing upwardly on the end portion 140from beneath the hub 100, to exert an upwardly-directed force on thespoke end fitting 104. The upwardly-directed force causes the tabs 124to urge the indented portions 138 inwardly, until the indented portions138 clear the tabs 124. At this point, the spoke end fitting 104 is freeto move upwardly, out of the pocket 122, in response to theupwardly-directed force on the spoke end fitting 104.

The bowl 102 is mounted on the hub 100 by way of the bowl adapter 106.The bowl adapter 106 is ring-shaped, as can be seen in FIGS. 34 and 35 .The bowl adapter 106 has a sidewall 160 and a first, or upper lip 162.The upper lip 162 adjoins the upper end of the sidewall 160, and extendsoutwardly from the sidewall 160 at an angle of about 90 degrees inrelation to the sidewall 160, as illustrated in FIGS. 36 and 37 .

The bowl adapter 106 also includes a second, or inner lip 166. The innerlip 166 has a first portion 168 a that adjoins the lower end of thesidewall 160, and extends inwardly from the sidewall 160 at an angle ofabout 90 degrees in relation to the sidewall 160. The inner lip 166 alsoincludes a second portion 168 b that adjoins the first portion 168 a,and extends upwardly and inwardly from the first portion 168 a, at anangle of about 12.5 degrees in relation to the vertical direction. Thesecond portion 168 b can have other orientations in alternativeembodiments. The inner lip 166 also includes a third portion 168 c thatadjoins the second portion 168 b, and extends upwardly from the second168 b.

Referring to FIGS. 26-29 , each corner portion 112 has a finger, orupper segment 170. The upper segment 170 forms the uppermost portion ofthe corner portion 112, and has a smaller width, or side-to-sidedimension, than the remainder of the corner portion 112. Each uppersegment 170 has an upper surface 172; and an angled surface 174 thatadjoins, and extends outwardly and downwardly from the upper surface172. Each upper segment 170 also includes two outwardly-facing tabs 176.The tabs 176 on each upper segment 172 are located below the angledsurface 174, on opposite ends of the upper segment 172. As can be seenin FIG. 28A, each tab 176 has an upwardly-angled surface 178 thatadjoins the angled surface 174; and a downwardly-angled surface 179.

Referring to FIGS. 22-25 and 37 , the bowl 102 has a ring-shapedprojection 180 extending from a bottom surface 182 thereof. The bowladapter 106 is retained on the bowl 102 by an interference fit betweenthe projection 180 and the bowl adapter 106. In particular, theprojection 180 is positioned and dimensioned so that the inwardly-facingsurface of the projection 180 contacts the outwardly-facing surface ofthe upper lip 162 of the bowl adapter 106; and the resulting frictionbetween the projection 180 and the upper lip 162 inhibits separation ofthe bowl adapter 106 from the bowl 102. The bowl adapter 106 can beretained on the bowl 102 by other means, such as adhesive or fasteners,in alternative embodiments.

The bowl 102 and the bowl adapter 106 can be installed on the hub 100 byaligning the center of the bowl 102 with the center of the hub 100, andmoving the bowl 102 toward the hub 100 so that the angled surface 174 ofeach corner portion 112 of the hub 100, and the upwardly-angled surfaces178 of the tabs 176 contact the second portion 168 b of the inner lip166 of the bowl adapter 106. Due to the resilience of the hub 100 andthe bowl adapter 106, and the angled orientations of the surfaces 174,176, further movement of the bowl 102 toward the hub 100 causes theinner lip 166 of the bowl adapter 106 to deflect outwardly, while theupper segments 170 of the hub 100 deflect inwardly.

Continued movement of bowl 102 toward the hub 100 eventually causes thetabs 176 to contact, and slide along the third portion 168 c of theinner lip 166, until the tabs 176 move past the third portion 168 c. Atthis point, the inner lip 166 and the upper segments 170 spring back, orreturn to their un-deflected positions. Once the inner lip 166 and theupper segments 170 have returned to their un-deflected positions,interference between the downwardly-angled surfaces 179 of the tabs 176,and the third portion 168 c of the inner lip 166 discourages separationof the bowl 102 from the hub 100.

When desired, the bowl 102 can be separated from the hub 100 pulling thebowl 102 and the hub 100 away from each other. The resulting interactionbetween the downwardly-angled surfaces 179 of the tabs 176 and the thirdportion 168 c of the inner lip 166 causes the inner lip 166 to deflectoutwardly while the upper segments 170 of the hub 100 deflect inwardly,allowing the tabs 176 to slide downward along the second and thirdportions 168 b, 168 c of the inner lip 166, until the tabs 176 havecleared the inner lip 166. At this point, the bowl adapter 106 and thebowl 102 are separated from the hub 100. Thus, the bowl 102 can bemounted on and removed from the hub 100 with a simple push-on, pull-offmotion, without a need for a twist-lock feature.
